Ultrasonic dissolution of brazing of 55% SiCp/A356 composites ZHANG Yang(张 洋), YAN Jiu-chun(闫久春), CHEN Xiao-guang(陈晓光), CUI Yan(崔 岩) State Key Laboratory of Advanced Welding Production Technology... was investigated. During the brazing process, ultrasonic vibrations were applied to samples for bonding and a significant dissolution of the filler metal into the matrix alloy in the base materials......
Dissolution behavior of Cu in Cu-Ag and Cu-P brazing alloys using weld brazingLI Yi-nan1, 2, WANG Chang-wen1, PENG Zi-long2, YAN Jiu-chun1, LIU Xue-song1(1. State Key Laboratory of Advanced Welding... of base metal Cu in the Cu-Ag and Cu-P brazing alloys using weld brazing was researched. The thickness loss of Cu foil in contact with Cu-P and Cu-Ag alloys at 800-920 °C was measured. And the dissolution......
Strengthening mechanism of ceramic particle reinforced bonds by ultrasonic brazing of AlMMCsLENG Xue-song1, WANG Chang-wen1, ZHANG Yang2, CHEN Xiao-guang1, YAN Jiu-chun1(1. State Key Laboratory... in the composite bonds. Therefore, with appropriate bonding parameters, ultrasonic brazing can make the SiC particles and Al contents increase in the bond, and this distribution will contribute......

Correlations between interfacial..., in which the formation mechanism of Cu6Sn5 is mainly controlled by diffusion, and the formation mechanism of Cu3Sn layer is controlled by the reaction. After applying ultrasonic, a crush-dissolution......
Effects of ultrasonic dispersion on structure of electrodeposited Ni coating on AZ91D magnesium alloy WU Hua(吴 化)1, ZHAO Guo-liang(赵国良)1, MU Jun-wei(穆君伟)2, LI Xue-song(李雪松)1, HE Yi(何 毅..., ultrasonic technology was applied in the processes of pre-treatment and electrodeposition. The phases of pre-treatment layer and the nickel coating were analyzed by X-ray diffractometry (XRD) and X-ray......
slightly changed. When vibration temperature is low, high volume fraction of solid in melt leads to the high melt viscidity which depresses the effect of ultrasonic vibration. A lower dissolution... Influence of high intensity ultrasonic vibration on microstructure of in-situ synthesized Mg2Si/Mg composites CHEN Ke(陈可), LI Zi-quan(李子全), ZHOU Heng-zhi(周衡志), WANG Wei(王伟) College of Materials......
